These great hollow globes of artificial super-metals, and artificial transparent adamant, ranged in size from the earliest and smallest structures, which were no bigger than a very small asteroid, to spheres considerably larger than the Earth. (Olaf Stapledon, STAR MAKER)

Wisps

Today's Astronomy Picture of the Day shows us a portion of the very beautiful (and impossible to see under my skies!) Veil Nebula in the constellation of Cygnus. Being in the circum-polar region, it is well placed to be seen much of the year from my locale but requires dark (and steady) skies as well as a emission filter to tease out details.
